Oscillator crystal input or external clock
source input. ST buffer when config-
ured in RC mode. CMOS otherwise.
External clock source input.

Oscillator crystal output. Connects to
crystal or resonator in crystal oscillator
mode.
In RC mode, OSC2 pin outputs
CLKOUT which has 1/4 the frequency
of OSC1, and denotes the instruction
cycle rate.
PORTA is a bidirectional I/O port.

Legend: TTL = TTL-compatible input CMOS = CMOS compatible input or output
ST = Schmitt Trigger input with CMOS levels
OD = Open drain output
SM = SMBus compatible input. An external resistor is required if this pin is used as an output
NPU = N-channel pull-up PU = Weak internal pull-up
No-P diode = No P-diode to V
DD AN = Analog input or output
I = input O = output
P = Power L = LCD Driver
